Hugo website engineer for multiple projects
I've been using freelancers for years and worked with a lot of devs. Anton is by far one of the best I've worked with. He was handed a complex Hugo/JS-task and solved with with high precision. Wish I can re-hire for our next job.

I design clean, modern UIs in Figma myself, then build them — no separate designer needed. Consistent vision from concept to production, fewer handoffs, faster iterations.

⚙️ How I work
1. Quick discovery — I ask the right questions before writing a line of code (scope, timelines, key risks)
2. Milestones with weekly demos — transparent progress, no surprises
3. Production-ready code — TypeScript strict, clean architecture, code your next developer will thank you for
4. Clear handover — documentation, post-launch support if needed
📩 Send me a message describing your project — I usually reply within a few hours with honest thoughts on approach, timeline, and risks.
Let's build something exceptional together.
